Digi user manual RCM4000 Features, Feature RCM4000 RCM4010

1.1 RCM4000 Features

•Small size: 1.84" × 2.42" × 0.77" (47 mm × 61 mm × 20 mm)

•Microprocessor: Rabbit 4000 running at 58.98 MHz

•Up to 29 general-purpose I/O lines configurable with up to four alternate functions

•3.3 V I/O lines with low-power modes down to 2 kHz

•Five CMOS-compatible serial ports — four ports are configurable as a clocked serial ports (SPI), and one port is configurable as an SDLC/HDLC serial port.

•Combinations of up to eight single-ended or four differential 12-bit analog inputs (RCM4000 only)

•Alternate I/O bus can be configured for 8 data lines and 6 address lines (shared with parallel I/O lines), I/O read/write

•512K flash memory, 512K SRAM, with a fixed mass-storage flash-memory option that may be used with the standardized directory structure supported by the Dynamic C FAT File System module

•Real-time clock

•Watchdog supervisor

There are two RCM4000 production models. Table 1 summarizes their main features.

Table 1. RCM4000 Features

Feature	RCM4000	RCM4010
Microprocessor	Rabbit® 4000 at 58.98 MHz
SRAM	512K
Flash Memory (program)	512K
Flash Memory	32 Mbytes (NAND flash)	—
(mass data storage)
A/D Converter	12 bits	—
	5 shared high-speed, CMOS-compatible ports:
	5 are configurable as asynchronous serial ports;
Serial Ports	4 are configurable as clocked serial ports (SPI);
	1 is configurable as an SDLC/HDLC serial port;
	1 asynchronous serial port is used during programming
	1 asynchronous serial port is dedicated for A/D converter (RCM4000)

The RCM4000 is programmed over a standard PC serial port through a programming cable supplied with the Development Kit, and can also be programed through a USB port with an RS-232/USB converter or over an Ethernet with the RabbitLink (both available from Rabbit Semiconductor).

Appendix A provides detailed specifications for the RCM4000.
